Above that, the bimetal strip heats earlier: 5.63 A at 40 °C, 5.44 A at 45 °C, 5.24 A at 50 °C, 5.04 A at 55 °C, and 4.82 A at 60 °C. If the panel ambient runs at 50 °C, this breaker will carry 5.24 A continuously before the thermal trip element starts to bend — not 6 A. Installation depth is 70 mm (total depth 76 mm). Sealable with a lead seal for tamper-evident applications.","metaTitle":"Siemens 5SY7506-8 SENTRON MCB, 6A D-curve, 15/40 kA","metaDescription":"Siemens 5SY7506-8 SENTRON miniature circuit breaker, 6 A rated, D tripping characteristic, 15 kA (EN 60898) / 40 kA (IEC 60947-2) breaking capacity.

The difference is the trip curve and rating: the 5SY7506-8 is a 6 A D-curve; the 5SY7210-7CC is a different rating and characteristic. Verify the branch-circuit protection requirements before swapping — the physical swap is straightforward, but the protection coordination may change."},{"question":"What compliance documentation does Siemens provide for 5SY7506-8?","answer":"Siemens provides RoHS and REACH declarations, manufacturer declarations of conformity to EN 60898 and IEC 60947-2, and the product is halogen-free and silicon-free.
